Tier tokens are necessary to participate in the Blind Well. There are 3 types of tokens you can get and they increase in difficulty. Tokens can drop from public events in the Dreaming City. They can be bought from Petra Venj too, but in order to purchase them, you’ll need Dark Fragments. You can get Dark Fragments from chests, public events, bounties from Petra, and patrols in the Dreaming City.

Tier I: This cost 5 Dark Fragments and it is the easier level out of the 3 Tiers.

Be sure that your Power level is at, near, or above 520. You’ll be able to do Tier I comfortably with your Fireteam and preferably with more players. Tier II will be tough and you should have at least 5 to 6 players if you are at 520 since enemies will be tougher than Tier 1. If you are doing Tier III, then you should be well above 520.

It is best to have Supers that do more damage on the boss. You could have supporting supers such as the Tether or Ward of Dawn, but no more than one person should have these on. Although, the Well of Radiance can come in handy when healing and empowering you and your allies.

Since the boss is a large Abomination, it will smash you if you get too close. You could use a close-range Super, but be sure to run away right when your super runs out. However, the Abomination can still attack you from a distance with its Arc ability so you aren’t completely safe if you stay away. Also, the Scorn will be all over the place and especially near the boss so make sure you are prepared for close and long-range combat.

When the boss’s shield is taken down, keep killing the Anathemas for the Harmony buff since it recharges your abilities faster.

To start the Blind Well, you go to the tall pillar in the middle and turn in your token. The activity always starts in the middle and progress to other zones within the area. A Tier is divided into 5 waves and you’re given 2:30 minutes for each wave.

The 1st wave is in the middle by the pillar. A large bubble will form over that zone protecting you from the toxic gas that's spreading through the area. Within the given time, you’ll need to deposit Light to the Well by defeating enemies. The same will have to be done for every wave except the final one.

The 2nd, 3rd, and 4th waves will be in different zones around the Blind Well. Players will get a Touch of the Sky buff that protects them for 5 seconds when they leave the zone to go to the next one.

In these waves, you’ll have to look for Anathemas which are glowy enemies that drop a Harmony orb. Whoever picks up the orb will have to attack the Servant of the Plague, a mini-boss, to take down its shield and kill it. Players who did not pick up the Harmony orb cannot remove the shield no matter what. However, everyone can attack the Servant of the Plague once the shield is down.

In the final wave, you’ll have to deal with a certain amount of bosses depending on the Tier difficulty. There won’t be any more bubbles or toxic gas, but getting the Harmony buff becomes crucial. Anathemas need to be taken down for the Harmony buff, then you can attack the Herald of the Plague, which is a large Abomination. The shield may not come down with one Harmony buff, but you’ll be able to find more Anathemas around.

Once the shield is down, everyone can focus on defeating the boss.

Each Tier grants a chest at the end of the activity, but Tier II and Tier III can drop a Seed of Light.
